The Coleoptera Found in a Barn. 



By H. \V. \VKNZKL, Philadelphia. 



The following list is the result of an experiment made during' 

 the month of May, 1900, with the object of determining the 

 Coleopterous fauna of an old barn. The building from which 

 the material was collected stands in the lower section of our 

 city, is an old wooden structure parti}' wrecked by age and no 

 longer in use for storing products. 



The usual species infesting stored grain were not found, with 

 the exception of the large Tenebrionid, '/'t'/nbn'o molitor, which 

 was in the pupa state in large numbers on May 2jth, changing 

 into the imago a few days later. All species of Histeridse were 

 taken under pieces of rotten wood covered by deep layers of 

 damp refuse. Probably the habits of these species account for 

 their scarcity in collections. 



The Latridiidge and Trogositidae were all sieved from dry 

 accumulated old hay and grain dust. 



The Ptinidae were found in a small annex formerly used for 

 cattle. The ground was a hard dried out conglomeration of 

 manure and dirt, almost like turf ; at first but few specimens 

 were found in it, but finally, by beating or thumping the ground. 

 both species mentioned below appeared in great numbers. 



Only species of which I have no doubt as inhabiting such 

 places and which were found mostly in numbers are placed in 

 this list. Several species of Carabidce were found, but only in 

 single numbers ; as they are probably accidentals they are 

 omitted. 



The following is an enumeration of the species found : 



Microglossa s|>., common in clamp places. 



Xantholinus gularis Lee., common with above sp. 



()/<>/)/in<in <>h/cc/uni Er., several examples. This species I have fre- 

 quently found in the immediate vicinity in low meadows. Other minute 

 species of Staphylinicke were taken which I am unable to determine. 



Ftenidinm evaiiesceiis Marsh, common, sieved from damp refuse. 



Sericoderus flavidus Lee., common, sieved from dry old hay. 



Mycetcea liiiia Marsh, very common everywhere. 



. \glenusbrunneus Gyll., common ; an interesting blind spccio. 



Silraims aih'cna Wattl., very common. 



Typhcea fumata Linn., common in damp refuse.
